TORPEDO-GUARD.

Application filed December 8, 1917.

To all whom it may concern:

Be it known that I, lWIAnoIN ZAJAC, a citizen of the United States, residing at Chicopee, in the county of Hampden and State of Massachusetts, have l11"611i36(l new and useful Improvements in Torpedo-Guards, of which the following is a specification.

This invention relates to a torpedo guard adapted to be applied to marine vessels and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a guard of the character stated which completely surrounds the hull of the vessel and which includes supports attached to the hull of the vessel and carrying two sets of rails. These rails are arranged one set within the other and are spaced apart. Each set of rails carries a series of vertically disposed spaced pickets and these pickets extend from points above the water line to points below the level of the water and consequently they protect the hull of the vessel above and below the water line against projectiles such as torpedoes or explosive shells.

In the accompanying drawings Figure 1 is a side elevation of the hull of a vessel with the guard applied.

Fig. 2 is a top plan view of the same.

Fig. 3 is a fragmentary transverse sectional view of the same.

Fig. 4 is a horizontal sectional view out on the line l4 of Fig. 3.

F 5 is a vertical sectional view out on the line of Fig. 3.

Fig. 6 is a fragmentary transverse sectional view of the guard.

As illustrated in the drawings the hull of the vessel is indicated at 1. Hangers 2 are applied to the sides and. bow and stern of the hull and are secured thereto by means of bolts 3. Braces l are interposed between the sides of the hull and the intermediate portions of the hangers and hold the same in spaced relation to the hull. Outstanding arms 5 are mounted at the intermediate and lower portions of the hangers. Rail seetions 6 are secured to the hangers 2 by means of clamps 7 and the said rail sections are in alinement with each other and the same distance below the upper end of the hangers thereby they form a continuous rail extending completely around the hull.

tions 8 are secured by means of suitable clamping devices 7 to the hangers 2 and constitute a continuous rail which extends completely around the hull. An upper and a lower set of rail. sections 6 and 8 is provided. These rail sections are provided with openings and pickets 9 passed vertically through the said openings the said pickets belng provided at their upper ends with heads 10 which rest upon the upper surfaces of the upper rail sections 6 and 8 and which normally are positioned above the surface of the water. The lower portions of the pickets 9 extend below the surface of the water. The pickets 9 are arranged in two sets one set passing through the upper and lower rail section 6 and the other set passing through the upper. and lower rail sections 8.' Therefore the two sets of pickets are spaced from each other.

In the event of an attack a projectile will strike the outer set of pickets whereby the projectile is exploded and the fragmentswhich may fly from the projectile are prevented from coming in contact with the hull 1 by the inner set of pickets 9. Inasmuch as the pickets are spaced from each other ample room is provided to permit the water to flow freely between the same and hence the presence of the pickets will not materially interfere with the progress or navigation of the hull of the vessel.

From the foregoing description taken in conjunction with the accompanying drawings it will be seen that a torpedo guard of simple and durable structure is provided and that the same will effectually protect the hull of the vessel to which it is applied and the presence of the guard upon the hull will not materially interfere with the progress or navigation of the hull.

Having described the invention what is claimed is l. A torpedo guard comprising hangers, outwardly disposed arms carried by the hangers, rail sections attached to the hang ers, rail sections attached to the arms, the said rail sections constituting complete rails which surround the hull and which are spaced from each other and vertically disposed pickets passing loosely through both sets of rail sections.

2. A torpedo guard comprising hangers,

outwardly disposed arms carried by the around the hull of a vessel and pickets passhangers, rail sections having clamping deing vertically and loosely through the rails vices applied to the hangers, rail sections and having ends which rest upon the upper having clamping devices applied to the arms, surfaces 01 the upper rail sections.

5 the said rail sections being spaced from each In testimony whereof I affix my signature.

other, the two sets of rail sections forming continuous rails Which extend completely MARCIN ZAJAC. [L. s.]
